Great to hear you're enjoying the store Izaak, and thanks for the tip.

Note that "Layout" mode causes all content from all modules to be hidden, so it's certainly not very useful when editing the site. Layout mode is primarily meant as a means of re-arranging modules on a page using the drag & drop method,
especially when there are either, lots of modules present, or some of them have very long content areas, making it otherwise hard to shift modules up and down past each other.
